The Boring Lava Field is an extinct Plio-Pleistocene volcanic field zone with at least 32 cinder cones and small shield volcanoes lying within a radius of 13 miles (21 km) of Kelly Butte which is approximately 4 miles (6 km) east of downtown Portland Oregon in the United States. The name is derived from the town of Boring Oregon which lies just to the southeast of the most dense cluster of lava vents.
